You apparently didnt read the news: http://kotaku.com/5628894/its-official-duke-nukem-forever-coming-from-gearbox-software
of course they still work. Duke Nukem Forever is still unreleased, there is only a promise to make it available.
No they don't. When a developer as established as Gearbox announces they've taken it up it will happen.
Imagine if this game turns out to be utter shite when it's finally released. There would be a lot of disappointed people
I heard someone on Daybreak say this is going to be better than when Sonic 2 was originally released on the Mega Drive and that it's fully endorsed by Steve Buscemi.
If they screw up the controls that can very well easily happen. I am hoping for Horror racing style controls.
